Interlay, a London-based blockchain firm, launched a Bitcoin (BTC)-based cross-chain bridge on Polkadot (DOT). Named interBTC (iBTC), the bridge allows the use of Bitcoin on non-native blockchains for decentralized finance (DeFi), cross-chain transfers and nonfungible tokens (NFTs), among others.
interBTC operates as a BTC-backed stablecoin, secured by a decentralized network of overcollateralized vaults, which according to Interlay, resembles MakerDAO’s DAI token, a stablecoin on the Ethereum blockchain.
